- For steel oil pans, apply a continuous bead 6.35 mm (0.25 in) thick of RTV sealer GM P/N 12378521 (Canadian P/N 88901148) to the topside of the new windage tray gasket. Apply the RTV sealant directly over the sealing bead.
- Install the NEW windage tray gasket onto the engine.
- Apply a continuous bead 6.35 mm (0.25 in) thick of RTV sealer GM P/N 12378521 (Canadian P/N 88901148) to the bottom side of the new windage tray gasket. Apply the RTV sealant directly over the sealing bead.
- For aluminum oil pans, apply a continuous bead 6.35 mm (0.25 in) thick of RTV sealer GM P/N 12378521 (Canadian P/N 88901148), ensuring that the sealer also completely fills the groove in the oil pan.
- To ensure proper sealing, apply additional sealer at the four points called out in the illustration (1).
- Install the oil pan and oil pan windage tray gasket - if applicable.
- Clean the oil pan bolts of all debris.
- Apply one drop of GM P/N 12345382 (Canadian P/N 10953489) to each bolt.
- Install the oil pan bolts.
- Install the oil level sensor.
Important: For aluminum oil pans, begin with step 4. For steel oil pans, skip steps 4 and 5.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
Tighten
Tighten the oil pan bolts to 14 N·m
(125 lb in).
Tighten
